WATER-oneself.

Application, filed November This invention relates to water closets and,more particularly to that class or type which embodies a flush-waterchamber under control of valve mechanism adapted for operation by thecloset seat whereby thorough flushing is automatically effected.

The primary object of the present improvements is to provide acompactflushing' apparatus more particularly, although not es' l0 sentially,adapted to the flush-water chambers of the above referred to type ofcloset bowls.

Another object is the provision of a flushing apparatus for installationin the flushwater chambers of closet bowls with direct connection intothe servicesupply pipe.

A further object is to provide a compact* ly arranged,practicallynoiseless and simply constructed, automatic llushingrapparatus which is tree of any tendency to siphonic action incident toflushing of the closet bowl or` disturbance in the service supply suchas obtains on opening a local faucet while the closet is in use.

automatically functions each time pressure is applied to-and removed`from-fthe closet seat, thereby obviating all necessity fori With theforegoing and other objects in view, this invention essentially consistsin the novel construction,` combination and ar rangement of partsconstitutingr thematters hereinafter specilically described` and`illustrated by the accompanying drawings which form a part hereof; butit is to be understood that changes, variations and. modiications, maybe resorted to without departing` from the scope of said invention orsacrificing any of the foregoing recited objects and advan 'tageousfeatures.

In the drawinp's Figxl is a vertical sectional view illustrative of onecomplete physical example of my invention; and,

Fig'. Il is a relatively enlarged vertical sec.- tion through the novelflushing apparatus and A still further object is the provision of` awater closet which. is foolproof .and that` a, 192s.` serial m1312074,`

associated parts,witl`1 the control valve in the shut-oft position.

Referring1 first, more particularly, to Fig.` 1 a `typical water closetbowl is comprehen-` sively designated by the numeral, the same affordinga water seal 6 and outlet 7 to which the sewer connection 8 is attachedin conventional manner. The bowl 5 is also characterized by an annular`chamber 9 about its top, designed to serve as a reservoir for` theflushing water `said chamber having com munication into a subjacentdistributor channel 10, by way of a port 11 in the separating` Wall orpartition 12, the flushing water dischargin(L into the bowl throughperfora` `tions 13, in the customary way.

For the purpose of controllingr the filling" of, and flushing-dischargefrom the chamber* 9, I make use of the noveliiushing mechanism `orapparatus, constituting the fundamentals y of the present invention, andnow to bede- `scribed in detail. V

Conveniently fitted to the upper end of the service pipe lllasbyscrewthreadingmis a" `tubular extension 115 ofa length toextend abovethe "horizontal median of the flushwater chamber 9, whereat it isexterior-ly screw-threaded `for secure attachment of a hollowclosure orcap 16, having a series of inflow ports 17 through the lower facelorvportion thereof. Thisfclosure cap 16 is pro- `vided with a centralinterior embossment `18. y

W l E y Concentric with the i aforesaid extensioni 15-and *upperend `of the service pipe 14- "is `a tubular fittingr 22"of largerdiameter that affords an annular "intervening space 23 for a purposelater on explained. This fitting 22 is provided at-the upper` end withadished flange 211 affording; a peripheralrib seat 25, as well as havinga series of openings `26 therethrough communicating into theflushwaterdischarge oort 11. It isnoticeable the tubular-fittingdlshed-iange 24 is somewhat v2fl cured in place'and rendered leaklproofbyaid of a suitable sealing gasket 31, as will be clearly understood bythose conversant with the art. Threadedly engagingthe outer on lower endofthe tubularv fitting 22v is a reducer nipple 32, the smaller,section33 whereof isa snug fit on the service 4pipe 14, and it is-'exfternally screwedgfor reception of.. afconventionatgland nut34,-andpacking: 35, whereby ,thecservice' connectionV is made watertight.

with 1Ethel result that'the stem'44 andiperforate bell 43Vare moveddownward carrying with them the sleeve member 36. As a consequence thedishcd 'flange 38 is moved away from the closure cap 16 to uncover thedischarge ports 17, thereby permitting service water pressure to elevatethe check valve 19 and flow through said ports-as well as via` theperforate bell 43 into the annular fiusl1-\vater chamber 9. At the sametime, the disk valve member 40 is forced into contact with thecooperative peripheral rib seat 25 ot the fitting ZZthereby,temporarily, closing discharge of water, by way of the openings Q6 andport 11, into the-distributor channel 10 and from thence to the bowl 5.lVith closure of the port 11, as just described, a certain amount Vofair will be trapped in the flush-water chamber 9 and compressed by theinrushing water from the service pipe 14, the flow of watercontinuinguntil an equalization of pressure obtains. lVhen the seat 50is released, incident to the user rising therefrom, the compressionspring 37 instantly functions to elevate the sleeve member 36 withresultant opening ofl the discharge port 11 and concurrent closure |ofthe inflow ports 17; whereas simultaneous elevation of the perfor-atebell 43 takes place with concurrent raising of theseat 50 by the stem 44to normal inactive or outr of use location. Incident to thc movementsset fort-h, the water collected in the chamber 9 is expelled via theopenings 26, andV discharge port 11, into the distributor channel 10 forforced dissipation through the perforations 13 about the closet bowl 5,breaking'thewater seal G, and effectively iiushing and siphoning out thecontents of said bowl via outlet 7, to sewer connection 8, suchoperation'being expedited under pressure of the air, previously trappedin the chamber 9, as described' above in connection vwith thevflush-water filling period. Incithe check valve 19will always be subjectto 'service pressure, with the result that said check valve 19 normallyabuts the embossment 18, or is lifted from its seat 21. This featureIdeem of vital importance in counteracting any possibility of siphonicaction setting' up through the apparatus when the seat 50 isreleased-consequent upon the opening'of a faucet, locally or otherwise,in the servicel connection while the closet is in use. lIty will beobvious that, instantly the balance of'pressure above and below thecheck valve 19'is disturbed, said valve will instantly seat itself underthe action of the compressed'air in the chamber 9 assisted by its ownweight o1' gravity; so that, on release of the seat 50, the sequence ofoperations above set forth are positively and automatically ensured.

Furthermore attention is directed to the fact that'my novel flushingapparatuscan be readily installed and quickly removed for inspection orreplacement through the aid Utl ltlfl lltl of the nipple 32, lock nut-3() and att-ach` `From the foregoing it will be apparent that I haveprovided a direct-acting flushing apparatus for water closets whichissin'iple in construction, automatic i'naction, and devoid of any partsliable to become deranged "or get out of order under constant use orcareless misuse.
